Hello it been a while. Hope everyone is doing well.? Can soome tell me which one is ABS Booster and ABS Pump ? There is conflict information out there, even in YT. See attached photo Thank you
Whatever they're called You better be replacing them as a pair like Toyota recommends or you might be paying labor twice just for fun
Thank you everyone. My pump keep making Zzzzzzz noises. I guess I bought the Booster as shown in picture 2.jpeg. I will look the pump.
Those are the exact noises it's supposed to make. Only a problem if it makes them at the wrong times or too often. If that's the case, the problem can still be in either of the two assemblies, so there's no one easy answer what will solve your problem. It's often the booster, as there are more valves inside there to go possibly bad.
Quick updates: I took the gamble and replaced just the booster it work. No more Zzzzz sounds from the pump, only when I step on the brake. However, all the ABS, traction lights come on and I did do the bleed job and it work great. Does anyone knows how to reset the lights without scan tools or Techstream tool ? Or let me know which cheap scan tools can do this job ? Please let me know. Thank you
You can buy a obd scan tool Fromm Walmart and write them down. Clear codes with the tool. If The codes comeback, continue troubleshooting using the codes as reference points
What did you use to properly bleed the system and set it up? You need techstream, or the D7, D8, or some other tool to set it up. And that tool will clear the codes. Without setting it up correctly, you run the risk of not having brakes. And causing a wreck, and injuring some innocent party....
You did NOT bleed the brakes correctly unless you used Techstream or similar scan tool. That is one reason the warning lights are now on. There are many threads in this forum about brake bleeding after replacing the brake actuator. Do a search and a lot of reading to learn more.
Here are some basics on doing this with Techstream An alternative is to have a dealer or qualified independent with experience in this procedure to do it for you.
Use the dealer if you don’t have Techstream to run the procedure. The op has already replaced the master cylinder.
Thank you, all. I order Techstream V18 and should arrive today. I will use the instruction rjparker provide. Thank you so much.
Installing Techstream requires a pc and the hardware interface you probably bought. The instructions above are once you get it installed which should have a separate set of instructions.
Updates: Installed tech stream and able to communictaion. Butwhen i get to the bleeding process i fail, see photo, Any suggestion ?
